Hand-bearing precision compasses
Suunto bearing compasses are designed to combine extreme accuracy with ease and speed of operation. The accuracy is 1/3°, graduation 1/2° and the compass weighs only 115 g. The flat, compact housing has no protruding parts and are designed to stand up to heavy-duty wear. The compasses are water resistant.
The cards of these compasses are immersed in a special dampening fluid that ensures vibration-less, smooth behavior. The compass card is set on an anti-magnetic pivot with jewel-bearing. The sintered special magnet guarantees long life-time for accuracy and smooth behavior. The liquid remains clear and maintains its viscosity low even in high temperature variations for years.
The compasses have been given permanent anti-static treatment. The lens apertures of the Suunto KB-14 and KB-20 types are restricted horizontally by a column, which automatically centers the eye on the optical axis, thus eliminating parallax.
There is also a rubber cover accessory for all the Suunto KB-14 versions that is made of a saltwater- and UV-resistant mixture of EPDM and natural rubber.
